Hi, anyone else getting this problem? I watch BT Sport using the App Extra and Chromecast to my TV. There are no issues watching live football, the picture is very clear and sound great. However, during the ads before kick-off and at half-time the picture freezes and a message appears on the TV saying my internet connection may be poor. There is nothing wrong with my internet connection, as the problem only happens when the ads are on and at no other time.
